    Company · Oxford

    Infleqtion UK, registered as ColdQuanta UK Ltd, is the British arm of the US neutral-atom company Infleqtion, which traps arrays of cold atoms with lasers for both computing and sensing and has worked in Oxford since 2014. It built a neutral-atom testbed for the National Quantum Computing Centre's 2024 testbed programme and in May 2026 delivered a 100-physical-qubit system to the centre at Harwell. It also won one of 14 Innovate UK sensing and navigation contracts in November 2025, and in September 2026 expanded its Oxford Technology Park site to house a Quantum Innovation Centre for research, production and systems integration.

    Infleqtion UK (ColdQuanta UK Ltd), based in Oxford, is a company. It leads 1 UK project (SQALE) and is a partner in 7 more.
